dynamic power management proliant

[Gijsen]

Using a Proliant ML350 G5 with 2 Intel Xeon 3G, ROM version 2.1: upon booting
the following message shows:
"Warning: Demand based power management cannot be supported with the following
Processor configuration. The system will run in Full Performance mode."

The bios is set to (power governor): Dynamic Power savings mode (auto)

As this is a warning the booting continues and windows starts up both the
server is rather noisy.
The support forums mention a cpqhealth driver that is supposed to handle this
issue but nowhere is mentioned where to get this driver for windows server 2003.
Or is there any other way to quiet down the server (its running full throttle
now)?

Hi,
i have the same issue on :

- DL380R04 X3.2/800-1M EURO
Processor 1 initialied at 3.20 Ghz /800 Mhz
Processor 2 initialied at 3.20 Ghz /800 Mhz
- hyperthearding enable
- bios version 02/12/2004 / PSP 7.20A
- Windows 2003 Server.

On the boot :
"Warning: Demand based power management cannot be supported with the following Processor configuration. The system will run in Full Performance mode."

Did you find a solution, or a workaround

Belowe is the anser I got from the HP support center (it didn't help me as my Intel Xeon 3G seems outdated):

Demand Based Power Management is a new feature in some of the Proliant server, but is not backwards compatible with older CPU models. It will be the followup on the original ACPI and is currently only supported with Windows 2003 SP1.

Advise is to use ACPI in your configuration, since your CPU does not support DBPM.

This feature however has not directly to do with the fancontrol.
The fancontrol is our own design, Demand Based Power Management is a design of Intel and Microsoft.

Offcourse indirectly the temperature of the CPU will determine the fanspeed, however these are 2 separate hardware controls.

To let the health agents take control some RBSU's have a fansetting. Check via F9 if under "Advanced Options" the "Default Fan Speed" is set to low.

You should hear a main difference when Windows is loaded. As the management agents are loaded, the software fancontrol takes over the hardwarecontrol and reduces the RPM's of the fan(s).

If you are still experience high fanspeeds, please check the temperatures via HP Integrated Management if they don't exceed the thresholds.
